Application filed. 24:, 1.919. fierial N0. 299, l36.

To all whom it may concern Be it known that T, ORMAND C. LILES, acitizen of the United States, residing at Goldsboro, in the county ofWayne and State of North Carolina, have invented new and usefulImprovements in Bed-Litters, ott' which the following is specification.

The present invention has reference to... 1a.... 'for 11-111 anc sus c12 (t 1 van l l tt g l Jenl 11g 1. wagon bed from the frame thereof, andthe primary object of the invention is to produce a device of thischaracter which shall be of a simple construction, strong and durable,and thoroughly ellicient for performing its :1 unctions.

it further object of the invention is to produce a wagon bed lifterwhich is in the nature ot a collapsible trestle so that the same may beeasily transported or stored, the parts thereoi being readily set up andeltectively held in operative position, while the lifting deviceconnected with the tr stle is of a simple, durable and easily operatedconstruction.

(lther objects and advantages will present themselves as the nature ofthe invention is better understood, reference being had to theaccompanying drawings, in which:

Figure 1 is a view showing the device in operative position.

Fig. 9. is a top plan view thereof".

F 3 is an end view thereotl Fig. 4C is a sectional view approximately onthe line 4 l oi? Fig. 1.

Fig. 5 is a perspective view of the device in its collapsed position.

As illustrated by the drawings, my improvement is in the nature of acollapsible trestle, comprising a horizontal beam and legs 11 which haveone of their ends pivotally secured to the sides of the beam at the endsthereof. One pivot may connect each oppositely disposed pair of legs,the said pivots being preterably in the nature of bolts 19. which areengaged by nuts 13, and by screwing the nuts on the bolts the properfrictional engagement between the legs and beams may be obtained. Inaddition to this, the tightening of the nuts on the bolts permits of thelegs being held against the sides of the beam when the device is incollapsed condition. The pivoted ends of the legs 11 are beveled as at14 and these beveled portions snugly engage with the sides of the beamwhen the legs are set up. Thelegs are retained at a desired out vardangle with respect to the ends of the beam by contact with studs 15which extend laterally from the sides of the beam. The legs are furthersustained in their set up position by pivotally connecting to one ofeach pair oil? legs a brace 16 that is provided with a notch 17 designedto engage with the stud 18 on the opposite leg.

The beam 10 is centrally provided with a vertically disposed elongatedslot 19, and passing through this slot is a link 20. The link 20 passesthrough an opening 21 in a head piece and is pivotally secured to thesaid head piece. The head piece is of a length a iproxiinately equalingthat ot the wagon bod and has depending from its sides, adja nt to itscorners flexible elements 241: having their outer ends provided withhooks that are designed to engage with the under edges of the body oithe wagon.

(in the beam 10, to one side of the link opening 19 therein there arisesa lug 2G. The outer end 0t this lug is preferably bi- :lt'urcated, andin the said bifurcation is an operating lever 2-7, the latter beingpivoted to the ]u as at 28 and being likewise pivoted to the link as at29. The outer end of the lever has suspended therefrom a chain 30, andone oi the links oil. this chain is designed to engage with the lug 31on one of the ends oi. the beam 10. By this arrangement it will be notedthat when pressure is exerted upon the free end of the lever and thehead piece raised to elevate the wagon body the said head piece may beretained at a desired elevation, which permits of the running gear ofthe wagon being drawn outward from beneath the body, and the said bodysustained in itselevated position for any desired length of time. Thebody may be readily lowered on the running gear as will, it is thought,be fully understood. When the device is not in use the same is collapsedby releasing the brace members from the legs and folding the legsagainst the sides of the beams 10. The chain is arranged to have anotherof its links engage with the leg 31 so as to hold the leversubstantially parallel to the longitudinal plane of the beam 10.

It is tl'iought, from the foregoing description, when taken inconnection with the drawings, the simplicity of the construction and theadvantages thereof will be readily apparent Without further detaileddescript10n. e
